K&N 69 Series Typhoon Intake Systems Reviews

My last few cars including my 2014 Altima S I opted for the K&N drop in filter,which made a difference over the oem filter. But the Typhoon intake is in a class of its own. Everything is improved,acceleration,drivability,fuel economy, and that sound! I love it!

K&N 57 Series FIPK Air Intake (50-State Legal) Reviews

The quality was very good, The installation was a pain. It was not hard, but there are a lot of bolts and brackets. It went from 15 MPG to 17 MPG with slightly more spirited driving on the 17. I noticed the acceleration is more responsive. That is a win-win in my book!
